Description

The present invention relates to a recording apparatus such as a video tape recorder which can program a recording table using a VCR+ code (Video+ code).

A video tape recorder (VTR) has been proposed which can program a recording table using a VCR+ code. The proposed VTR operates as follows: When the VTR receives a VCR+ code, it decodes the VCR+ code to obtain the date and/or time at which a broadcast program starts, a time at which the broadcast program ends, and a VCR+ guide channel (second broadcast station code), and then writes the date and/or time at which the broadcast program starts, the time at which the broadcast program ends, and a VTR channel number and/or VTR position number corresponding to the VCR+ guide channel.

In order to convert the VCR+ guide channel into a corresponding VTR channel number and/or VTR position number, the VTR has a memory device for storing data representing the relationship between VCR+ guide channels and VTR channel numbers and/or position numbers.

As described above, the storage device is required to store data representing the relationship between VCR+ guide channels and VTR channel numbers and/or VTR position numbers. As shown in Fig. 11 of the accompanying drawings, a menu displaying such data is displayed on the screen of a television monitor device 100 of a VTR 50. In viewing the displayed menu, the user operates buttons on a remote control (transmitter) 60 or the VTR 50 itself to enter a channel number corresponding to a desired VCR+ guide channel. This practice is However, this is very cumbersome. WO-A-90/00847 describes a similar technique in which conversion data between station names and local channel numbers is entered into a memory by the user.

VPS codes are also known, which are digital data transmitted with a broadcast video signal in the vertical synchronization interval to identify the broadcast signal. For example, the article by Dietmar Lerch in Radio Fernsehen Elektronik, Vol. 40, No. 11, 1991 on pages 677-679 entitled "Sender programming with ALS-Plus" discloses an automatic scan of tuning frequencies to detect broadcast stations, identify them by their VPS codes and thereby create a display table that shows the user which broadcast channel is being received on which tuning channel.

According to one aspect of the present invention, there is provided a recording apparatus comprising: a tuner which outputs broadcast signals of respective stations received on respective channels selectable by the tuner, means for decoding VCR+ codes input to the recording apparatus to obtain VCR+ guide channel codes identifying respective broadcast stations to be recorded by the recording apparatus, and storage means for storing data representing a first correspondence relationship between the tuner-selectable channels and the VCR+ guide channel codes, broadcast station code detector means for detecting broadcast station codes identifying respective broadcast stations from television broadcast signals of channels selectable by the tuner, second storage means for storing data representing a second correspondence relationship between the VCR+ guide channel codes and the broadcast station codes, and processing means for setting and storing the data representing the first correspondence relationship using the data received from the broadcast station code detector device 4 and the data representing the second correspondence relationship in the first-mentioned storage device.

As a result, the present invention can provide a recording apparatus capable of automatically setting data representing the corresponding relationship between channels selectable by a tuner and VCR+ guide channels.

In one embodiment, the recording device comprises a remote-controlled recorder and a remote control transmitter for remotely controlling the recorder, the recorder comprising the broadcast station code detector device, the first storage device and the processing device, and the transmitter comprising the second storage device. In another embodiment, the recording device comprises a remote-controlled recorder and a remote control transmitter for remotely controlling the recorder, the recorder comprising the broadcast station code detector device, the first storage device, the processing device and the second storage device.

According to another aspect of the present invention there is provided a method of setting channels of a recording apparatus comprising: a tuner which receives and outputs broadcast signals of respective stations on respective channels selectable by the tuner, means for decoding VCR+ codes input to the recording apparatus to obtain VCR+ guide channel codes identifying respective broadcast stations to be recorded by the recording apparatus, and storage means for storing data representing a first correspondence relationship between the tuner-selectable channels and the VCR+ guide channel codes, characterized in that the method consists of detecting broadcast station codes identifying respective broadcast stations from television broadcast signals on channels selectable by the tuner, storing data representing a second correspondence relationship between the VCR+ guide channel codes and the broadcast station scodes, in a second storage device, and setting and storing the data representing the first correspondence relationship using the broadcast station codes detected by the broadcast station code detecting device and the data representing the second correspondence relationship in the first-mentioned storage device.

Fig. 1 shows a block diagram of a recording device according to an embodiment of the present invention, which is typically in the form of a video tape recorder (VTR) combined with a remote control. The recording device uses VPS data as broadcast codes inserted into television broadcast signals.

The VPS data is described in detail below. Television broadcast signals in European countries, including Germany, Austria, Switzerland, the Netherlands and neighboring countries that can receive broadcast radio waves from these European countries, contain program information called VPS (Video Program System) which is written into the sixteenth H of a vertical synchronization interval. of the television broadcast signal. Fig. 4 shows the signal format of the VPS data.

The VPS data contains a series of data consisting of 15 words = 120 bits (1 word = 8 bits). The first word is a synchronization signal called CRI (Clock Run In), and the second word is a start code. Effective data is represented by the third to fifteenth words. Current program information is represented by the fifth and eleventh to fourteenth words. These words are given by the following meanings (see Fig. 5):

5th word: Audio multiplex information 2 bits

11th word: Address information 2 bits Information regarding a date on which the broadcast program starts 5 bits

Information regarding a month in which the broadcast program starts 1 bit

12th word: Information regarding a month in which the broadcast program starts 3 bits

Information regarding a time at which the broadcast program starts 5 bits

13th word: Information regarding a minute at which the broadcast program starts 6 bits

Information regarding the nationality of the broadcasting station 2 Bits

14th word: Information regarding the nationality of the broadcasting station 2 bits

The broadcast station identifying information 6 bits

The recording device shown in Fig. 1 is described below. According to Fig. 1, a broadcast signal received by an antenna 1 is fed to a tuner 2, which has a intermediate frequency amplifier, a video signal detector, etc. The tuner 2 is also supplied with a tuner control signal, such as a station selection voltage, from a VTR microprocessor 3. The tuner 2 supplies a data signal, such as an AFT signal, to the VTR microprocessor 3.

The tuner 2 supplies an output video signal SV to a video recording circuit 5 and a broadcast station code detector 4. The operation of the video recording circuit 5 is controlled by the VTR microprocessor 3. The broadcast station code detector 4 outputs VPS data inserted in the sixteenth H of the vertical synchronization interval of the video signal SV and also detects the broadcast station code represented by the fourteenth word (see Fig. 5). The broadcast station code detected by the broadcast station code detector 4 is supplied to the VTR microprocessor 3.

The recording device also has memories 6, 7. The memory 6 stores in advance data representing the corresponding relationship between broadcast station codes that can be detected from the vertical synchronization interval of the video signal SV and the VCR+ guide channels. For example, the data representing the corresponding relationship between broadcast station codes and VCR+ guide channels can be stored in the memory 6 when the recording device is shipped from the factory. The memory 7 stores data representing the corresponding relationship between channels that can be selected by the tuner 2 and VCR+ guide channels in an automatic tuning, as described later.

Connected to the microprocessor 3 is an infrared radiation detector 8 for detecting an infrared remote control signal emitted from a remote control 9. The detected remote control signal is supplied from the infrared radiation detector 8 to the VTR microprocessor 3. Also connected to the VTR microprocessor 3 is an input key circuit 10 which has keys which the user can press. ken to send the same control signals as can be emitted by the remote control 9.

A recording table program memory 11 connected to the VTR microprocessor 3 stores program information including a date and/or time at which a broadcast program starts, a time at which the broadcast program ends, and a channel when a recording table is programmed.

The microprocessor 3 controls a display circuit 12 for displaying on a screen to control the display of information on a television monitor device 13.

When the user presses a VCR+ automatic guide channel setting button on the input button circuit 10 or a setting button on the remote control 9, a VCR+ automatic guide channel setting process is automatically executed. Alternatively, as shown in Fig. 2, the user can execute a VCR+ automatic guide channel setting process by moving a displayed cursor for "AUTOMATIC VCR+ GUIDE CHANNEL SETTING" in a menu displayed on the screen of the television monitor device 13 with a button on the input button circuit 10 or the remote control 9 and then pressing an execution button.

The process for automatically setting a VCR+ guide channel is carried out according to the flow chart in Fig. 3.

First, the VTR microprocessor 3 controls the tuner 2 to select a channel of a smallest number of channels that the tuner can select at a step 20. Then the control goes to a step 21.

At step 21, the VTR microprocessor 3 determines whether a broadcast signal is present in the selected channel based on a data signal from the tuner 2. If a broadcast signal is present, the VTR microprocessor 3 checks a broadcast station code in the video signal SV at step 22 based on a detected output signal from the broadcast station code detector 4, after which the control goes to a step 23.

At step 23, the VTR microprocessor 3 determines whether a broadcast station code has been present. If a broadcast station code has been present, the VTR microprocessor 3 reads a guide channel corresponding to the detected broadcast station code from the memory 6 based on the data stored in the memory 6 representing the corresponding relationship between broadcast station codes and VCR+ guide channels. Then, the VTR microprocessor 3 writes the guide channel into the memory 7 in relation to the channel selected at step 24. Thereafter, control goes to step 25.

If there has been no broadcast station code, the VTR microprocessor 3 writes data representing "GUIDE CHANNEL NOT TUNED" in the memory 7 with respect to the channel selected at a step 26. Thereafter, control proceeds to step 25.

If there is no broadcast signal at step 21, the VTR microprocessor 3 writes data representing "NO BROADCAST" into the memory 7 with respect to the channel selected at step 27. Thereafter, control proceeds to step 25.

At step 25, the VTR microprocessor 3 determines whether all channels have been selected. If all channels have not been selected, the VTR microprocessor 3 controls the tuner 2 at step 28 to select a channel whose channel number is increased by "1". Thereafter, control returns to step 21.

When all channels have been selected at step 25, control goes to step 29 where the VTR microprocessor 3 displays channels one channel at a time on the television monitor 13 and prompts the user to enter guide channels using the input key circuit 10 or the remote control 9. Thereafter, the automatic tuning process is completed.

In the above automatic tuning process, the memory 7 thus stores data representing the corresponding relationship between tuner 2 selectable channels and VCR+ guide channels.

A recording table is programmed using a VCR+ code as follows: When a VCR+ code for a broadcast program whose recording table is to be programmed is input through the input key circuit 10 or the remote control 9, the VTR microprocessor 3 decodes the VCR+ code to obtain a date and/or time at which the broadcast program starts, a time at which the broadcast program ends and a VCR+ guide channel, and then writes the date and/or time at which the broadcast program starts, the time at which the broadcast program ends and a VCR+ channel number and/or VTR position number corresponding to the VCR+ guide channel into the recording table program memory 11. To convert the VCR+ guide channel into a channel selectable by the tuner 2, the VTR microprocessor 3 refers to the data which the represent corresponding relationship between tuner 2 selectable channels and VCR+ guide channels.

Since the data representing the corresponding relationship between channels selectable by tuner 2 and VCR+ guide channels is automatically stored in memory 7, the user does not have to go to the trouble of setting such data.

In the embodiment shown in Fig. 1, the number of channels in the automatic setting process varies successively from the minimum value to the maximum value. However, the number of channels may vary in a sequence in that all channels may be selected. The user can enter channels for which guide channels are to be set channel by channel using the remote control 9 or the key input circuit 10. The remote control 9 emits an infrared signal to the VTR in the embodiment shown. However, the remote control 9 may emit an ultrasonic signal, an RF signal, or a signal or the like, or can transmit an electrical signal if it is a wired remote control.

A recording apparatus according to another embodiment will be described below with reference to Figs. 6 and 7. Those parts shown in Figs. 6 and 7 that are identical to the parts shown in Fig. 1 are designated by the same reference numerals and will not be described in detail below.

In this embodiment, as shown in Fig. 7, a remote control unit 9 has a memory 6 for storing data representing the corresponding relationship between broadcast station codes and VCR+ guide channels, and a memory 7 for storing data representing the corresponding relationship between channels that can be selected by the tuner 2 and VCR+ guide channels.

Referring to Fig. 6, an infrared radiation emitter 14 connected to the VTR microprocessor 3 emits an infrared signal to the remote control 9. A memory 15 is used to store data representing the corresponding relationship between channels that can be selected by the tuner 2 and broadcast station codes. The other details of the recording apparatus shown in Fig. 6 are the same as those of the recording apparatus shown in Fig. 1.

According to Fig. 7, the remote control 9 comprises a microprocessor 9a to which the memories 6, 7 are connected, an input key circuit 9b connected to the microprocessor 9a, a display unit 9c which may be a liquid crystal display panel connected to the microprocessor 9a, an infrared radiation emitter 9d connected to the microprocessor 9a for emitting an infrared signal to the VTR and an infrared radiation detector 9e connected to the microprocessor 9a for detecting an infrared signal from the VTR.

When the user presses a setting button for setting an automatic VCR+ guide channel on the input button circuit 9b of the remote control 9, a process an automatic setting of a VCR+ guide channel.

Figures 8 and 9 illustrate a sequence for automatic setting of VCR+ guide channels on the remote control with the recorder shown in Figure 6.

First, the microprocessor 9a determines whether or not the VCR+ automatic guide channel setting key on the input key circuit 9b of the remote control 9 is pressed at step 9. If not, the control goes to step 45.

When the VCR+ automatic guide channel setting button is pressed in step 30, data indicating a minimum channel number of channels selectable by the tuner 2 is supplied from the infrared radiation emitter 9d to the VTR in step 31.

Then, the microprocessor 9a determines at step 32 whether or not data is being transmitted from the VTR through the infrared radiation detector 9e. If not, the microprocessor 9a determines at step 33 whether or not a certain period of time has elapsed. If it has not elapsed, control returns to step 33.

When it has elapsed, the microprocessor 9a displays the data "NO VTR RESPONSE" on the display unit 9c and interrupts the automatic adjustment process at step 34, after which the control goes to step 45.

If data is transmitted from the VTR at step 32, the microprocessor 9a determines at step 35 whether the data represents "STATION UNSELECTIBLE". If the data represents "STATION UNSELECTIBLE", the microprocessor 9a displays the data "STATION UNSELECTIBLE" on the display unit 9c and interrupts the automatic setting process at step 36, after which the control goes to step 45.

If the data does not represent "STATION NOT SELECTABLE" at step 35, the microprocessor 9a determines whether the data is a broadcast station code or not at step 37. If the data is a broadcast station code, the microprocessor 9a reads a code associated with the detected broadcast station. tion code from the memory 6 on the basis of the data stored in the memory 6 representing the corresponding relationship between the broadcast station codes and VCR+ guide channels. Then, the microprocessor 9a writes the guide channel into the memory 7 in relation to the channel selected at a step 38. Thereafter, control goes to a step 42.

If the data at step 37 is not a broadcast station code, the microprocessor 9a determines at step 39 whether or not the data is representative of "NO BROADCAST". If the data represents "NO BROADCAST", the microprocessor 9a writes data representing "NO BROADCAST" into the memory 7 in relation to the channel selected at step 40. Thereafter, control proceeds to step 42. If the data does not represent "NO BROADCAST", the microprocessor 9a writes data representing "NO BROADCAST STATION CODE" into the memory 7 in relation to the channel selected at step 41. Thereafter, control proceeds to step 42.

At step 42, the microprocessor 9a determines whether the channel numbers of all the channels have been transmitted to the VTR or not. If the channel numbers of all the channels have not been transmitted, the microprocessor 9a transmits a channel number increased by "1" by the infrared ray emitter 9d to the VTR at step 43, and control returns to step 32.

When the channel numbers of all channels have been transmitted at step 42, control goes to step 44, where the microprocessor 9a displays on the display unit 9c one by one channels for which there are no broadcast station codes and prompts the user to input guide channels using the input key circuit 9b. After that, the automatic setting process is completed and control goes to step 45.

At step 45, the processor 9a executes other processes of the remote control 9. Then the control returns to step 30.

Figure 10 shows the manner in which the VTR operates in a process for automatically setting VCR+ guide channels.

First, the VTR microprocessor 3 determines at step 71 whether a channel number is received by the infrared radiation detector 8 from the remote control 9. If none is received, control proceeds to step 81.

If one is received, the VTR microprocessor 3 determines whether or not a channel can currently be selected at a step 72. If not, the VTR microprocessor 3 transmits data representing "CHANNEL NOT SELECTABLE" to the remote controller 9 through the infrared ray emitter 14 at a step 74. Thereafter, the control jumps to the step 81.

If a channel is selectable in step 72, the VTR microprocessor 3 controls the tuner 2 to select a channel whose channel number was transmitted from the remote control 9 in step 73, followed by a step 75.

At step 75, the VTR microprocessor 3 determines whether there is a broadcast signal in the selected channel based on a data signal from the tuner 2. If there is no broadcast signal, at step 77 the VTR microprocessor 3 transmits data representing "NO BROADCAST" to the remote controller 9 through the infrared radiation emitter 14. Thereafter, control goes to step 81. If there is a broadcast signal, at step 76 the VTR microprocessor 3 checks a broadcast station code in the video signal SV based on a detected output signal from the broadcast station code detector 4, after which control goes to step 78.

At step 78, the VTR microprocessor 3 determines whether there was a broadcast station code. If there was a broadcast station code, the VTR microprocessor 3 transmits the broadcast station code to the remote controller 9 through the infrared radiation emitter 14 at step 79. Then, control goes to step 81.

If there was no broadcast station code at step 78, the VTR microprocessor 3 transmits data indicating "NO BROADCAST STATION CODE" to the remote controller through the infrared ray emitter 14 at step 80. Then, control goes to step 81.

At step 81, the VTR microprocessor 3 executes other processes of the VTR. Then, control returns to step 71.

As a result, in the above operation, the memory 7 of the remote control 9 stores data representing the corresponding relationship between channels selectable by the tuner 2 and VCR+ guide channels.

According to this invention, a table using a VCR+ code is programmed as follows: When a VCR+ code for a broadcast program whose recording table is to be programmed is input through the remote controller 9, the microprocessor 9a decodes the VCR+ code to obtain a date and/or time at which the broadcast program starts, a time at which the broadcast program ends, and a VCR+ guide channel. Then, the microprocessor 9a converts the VCR+ guide channel into a channel selectable by the tuner 2 by referring to the data stored in the memory 7 representing the corresponding relationship between channels selectable by the tuner 2 and VCR+ guide channels. Then, the microprocessor 9a transmits data indicating the date and/or time at which the broadcast program starts, the time at which the broadcast program ends, and the VCR+ guide channel to the VTR through the infrared radiation emitter 9d. The VTR microprocessor 3 then writes the transmitted data into the recording table program memory 11.

When a VCR+ code for a broadcast program whose recording table is to be programmed is entered through the input key circuit 10, the VTR microprocessor 3 decodes the VCR+ code to obtain a date and/or time at which the broadcast program starts, a time at which the broadcast program ends, and a VCR+ guide channel. Then, the VTR microprocessor 3 transmits the data of the VCR+ guide channel to the remote controller 9 through the infrared radiation emitter 14. The microprocessor 9a of the remote controller 9 converts the VCR+ guide channel into a channel selectable by the tuner by referring to the data stored in the memory 7 representing the corresponding relationship between channels selectable by the tuner 2 and VCR+ guide channels. Then, the microprocessor 9a transmits channel data to the VTR through the infrared radiation emitter 9d. The VTR microprocessor 3 then writes the data representing the date and/or time at which the broadcast program starts, the time at which the broadcast program ends, and the VCR+ guide channel into the recording table program memory 11.

Since the data representing the corresponding relationship between channels selectable by the tuner 2 and VCR+ guide channels is automatically stored in the memory 7 of the remote control 9, the user does not need to set such data.

In the embodiment shown in Figs. 6 and 7, the channel number varies successively from the minimum value to the maximum value and is transmitted from the microprocessor 9a of the remote control 9 to the VTR in the automatic setting process. The channel number may, however, vary in any order insofar as all channels are selected. The user can input channels for which guide channels are to be set one by one using the input key circuit 9b of the remote control 9. The remote control 9 uses infrared radiation signals for bidirectional communication between the remote control and the VTR. Such bidirectional communication may, however, be carried out using an ultrasonic signal, an RF signal or the like, or using an electrical signal if a wired remote control is provided. A wired remote control can only be used in the automatic setting process.

The VTR microprocessor 3 controls the tuner 2 to select a channel whose channel number has been transmitted from the remote controller 9, and the broadcast station code detector 4 detects a broadcast station code. However, as shown in Fig. 6, in the VTR having the memory 15 for storing data representing the corresponding relationship between channels that can be selected by the tuner 2 and broadcast station codes, a channel need not be selected by the tuner 2, and a broadcast station code can be designated for and transmitted to the remote controller 9.

The remote control 9 transmits channel numbers one by one to the VTR. However, the remote control 9 can transmit all channel numbers at once and receive result data indicating whether or not there is a broadcast station code from the VTR.

In the above embodiments, broadcast station codes are detected from VPS data inserted into a vertical synchronization interval of a television broadcast signal. However, EDS data in the United States, or PDC data in England, or character-multiplexed broadcast data may be detected and used to detect broadcast station codes.

In the present invention, broadcast station codes detected by the broadcast station code detecting means and the corresponding relationship between VCR+ guide channels and broadcast station codes stored in the storage means are used for the processing means for automatically setting the corresponding relationship between channels selectable by the tuner and VCR+ guide channels. As a result, it is not necessary for the user to take the trouble of setting the corresponding relationship.

While certain preferred embodiments of the present invention have been shown and described in detail, it is to be understood that numerous changes and modifications may be made without departing from the scope of the appended claims.
